[TR] Push or pull

[THOMAS FANSHER]

I'll do some checking on the electric fans, they "seem" to turn fine, but 
the temp gauge does climb when it's hot (90+) and I try to use the York 
compressor/Triumph a/c unit.
Friday at Jekyll Island we went on a driving tour to St. Simon's Island and 
had lunch. It started to rain and so in the low 80's with the a/c on doing 
about 45 mph there was no increase in temp.  I always assumed that 90 was an 
extremely hot day in the UK and Stags weren't designed to cool enough at 
temps above 85 or so F.  I've recored the radiator but have not replaced the 
two pusher fans. I've threatened to replace the compressor with a modern 
rotary one, but may try substitute fans first.
Thanks
Tom
